## Summary by CodeRabbit

- **New Features**
- Added the ability to replace attachments directly from the toolbar,
allowing users to select and update files seamlessly.
- **Bug Fixes**
- Improved handling when replacing embedded attachments with unsupported
file types, ensuring the view falls back to a card view as needed.
- **Tests**
- Introduced end-to-end tests to verify attachment replacement and
correct UI behavior in both standard and edgeless editing modes.
